P0361 Code, 94 Lumina, 3.8L

[discnik]

We have a 94 Lumina, 3.8L, vin"L". Pulled codes, P0361 EST line not toggling, & P0321 No 18X ignition pulse. The vehicle originally came in with a no start problem. Had a cam sensor code and the afore mentioned codes. Thought perhaps the 361 & 321 had to do with the crank sensor. Replaced both sensors. Vehicle will start and run but under accelleration has severe missing problem. Also replaced plug wires as there was arcing visible. Waiting on a EGR valve, code P0406, EGR pintle position error. Main question has anyone ran across the 361 & 321 codes ? If so what do they pertain to ? Especially the 361 code. Thanx.

IN my book P0361 reads: ignition coil K malfunction....and P0321 is ignition coil/engine speed input circuit range/performance..so it figures with your perception of "missing"..one coil or ignition module could be suspect. Just for a test, I'd swap a pair of coils one for the other (taking note of the proper markings) just to see if the error code will change with the coil position.

Thanks for the input. By the way what "book" did you look this up in ?

By the way, your interpretation of P0321 and the one I gave are near equivalents.
